Multi-Purpose Missiles are special-purpose munitions designed to be fired by missile launchers mounted on battle armor. Created by Clan Goliath Scorpion for their Undine battle suits, these missiles utilize an amphibious propulsion system which allows them to be fired both underwater and above-water. The addition of this dual function however makes multi-purpose missiles weigh twice as much as comparable SRM or LRM missiles. The missiles are sometimes designated SRM/T or LRM/T to denote their unique function.[1]
